I'm not sure Wyndham is the best example since they've had a VIP system for much of their existence.
True, but their VIP levels have changed at least once recently. Some folks who were once VIPs no longer are, and others now find themselves at a lower level than they enjoyed before.
The
Wyndham Access program referred to above is a relatively new type of ownership for Wyndham, but not the only new type of preferential system applied to already-existing resorts.
They also have
Presidential Reserve, which are specific units bookable mostly only by owners of Presidential Reserve points (think DVC making GV's available only to a new class of ownership). Only if those villas are not taken close to arrival do they become available to the common folk.
They also now have
Wyndham Club Pass, which took many Worldmark properties away from Wyndham owners and made them available only to Club Pass owners. At the same time, they added a bunch of Worldmark resorts which had not previously been available to Wyndham owners.
So that's at least three
new preferential systems Wyndham has put in within the last 3-4 years,
in addition to their VIP program -- and all of them offer booking advantages over "regular" owners, including resale purchasers.
Much of the availability in those new programs came from points Wyndham has "taken back" via foreclosure or deeds in lieu of foreclosure. Other points come from other timeshares they have purchased in numerous locations around the country during the recent recession (Reunion, Smuggler's Notch, their NYC, Chicago, and San Francisco properties, etc, etc.). And now, they have even started a program called "Ovation" to
repurchase points from current owners at a decent price.
All of the points from those various sources go into one of the three programs above and are sold only direct. So, rather than DVC using ROFR only occasionally, Wyndham is actively buying back points to repackage and sell with new booking advantages to the new buyers.
Wyndham is a Florida company, so I'm sure their approaches fit comfortably within Florida law.
